New guinea Impatiens plant named ‘Dongimeguinpin’

ABSTRACT

A new and distinct cultivar of Impatiens plant named ‘Dongimeguinpin’ characterized by its upright to outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; dense and full appearance; dark green-colored leaves with dark red-colored lower surfaces; freely and early flowering habit; medium-sized single-type bright salmon pink-colored flowers; and good garden performance.

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DONGIMEGUINPIN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri and hereinafter referred to by the name ‘Dongimeguinpin’.

The new Impatiens plant is a product of a planned breeding program conducted by the Inventor in Koka, Ethiopia and Encinitas, California. The objective of the breeding program is to create new freely-branching, early and freely flowering New Guinea Impatiens plants with large attractive flowers and good garden performance.

The new Impatiens plant originated from a cross-pollination made by the Inventor in November, 2017 in Koka, Ethiopia of Impatiens hawkeri ‘Dongimprolhopin’, disclosed in U.S. Plant Pat. No. 32,148, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN13-002477-003, not patented, as the male, or pollen, parent. The new Impatiens plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Encinitas, California in April, 2018.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, California since June, 2018 has shown that the unique features of this new Impatiens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylight and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dongimeguinpin’. These characteristics in combination distinguish ‘Dongimeguinpin’ as a new and distinct Impatiens plant:

-   -   1. Upright to outwardly spreading and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit; dense and full appearance.     -   4. Dark green-colored leaves with dark red-colored lower         surfaces.     -   5. Freely and early flowering habit.     -   6. Medium-sized single-type bright salmon pink-colored flowers.     -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent, ‘Dongimprolhopin’. Plants of the new Impatiens differ primarily from plants of ‘Dongimprolhopin’ in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than and not as         compact as plants of ‘Dongimprolhopin’.     -   2. Plants of the new Impatiens have smaller flowers than plants         of ‘Dongimprolhopin’.     -   3. Petal margins of plants of the new Impatiens are slightly         undulate whereas petal margins of plants of ‘Dongimprolhopin’         are undulate and ruffled.     -   4. Flowers of plants of the new Impatiens are bright salmon pink         in color whereas flowers of plants of ‘Dongimprolhopin’ are         reddish purple in color with lighter purple-colored centers.

Plants of the new Impatiens can be compared to plants of the male parent selection. Plants of the new Impatiens differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are not as vigorous as plants of         the male parent selection.     -   2. Flowers of plants of the new Impatiens are bright salmon pink         in color whereas flowers of plants of the male parent selection         are hot pink in color with darker pink-colored centers.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Kialdan’, disclosed in U.S. Plant Pat. No. 14,029. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Kialdan’ in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         ‘Kialdan’.     -   2. Lower leaf surfaces of plants of the new Impatiens are dark         red in color whereas lower leaf surfaces of plants of ‘Kialdan’         are green in color.     -   3. Plants of the new Impatiens have larger flowers than plants         of ‘Kialdan’.     -   4. Flowers of plants of the new Impatiens are bright salmon pink         in color whereas flowers of plants of ‘Kialdan’ are light purple         in color with white-colored centers.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Duemagwis’, disclosed in U.S. Plant Pat. No. 26,782. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duemagwis’ in the following characteristics:

-   -   1. Plants of the new Impatiens are more upright and more         vigorous than plants of ‘Duemagwis’.     -   2. Plants of the new Impatiens have smaller flowers than plants         of ‘Duemagwis’.     -   3. Flowers of plants of the new Impatiens are bright salmon pink         in color whereas flowers of plants of ‘Duemagwis’ are light red         in color.
